Exclamation pl2303 does not recognize my USB-Serial Controller

Hi.

pl2303 does not seem to recognize the USB-Serial Controller I wanted to work on. After much googling, these are the things I have already done that have failed:
1. Add vendor (0x04b8) and product ID (0x0d01) in pl2303.h
2. Add the necessary { USB_DEVICE(EPSON_VENDOR_ID, EPSON_PRODUCT_ID) }
to the usb_device_id table in pl2303.c
3. Recompile the kernel and reboot
4. modprobe usbserial and pl2303

I am using redhat 9.0 kernel 2.4.20-8.

Maybe I missed something?

Thanks!
